5 min read · June 2026

Need to turn an image into a PDF? Whether it's a photo, screenshot, scanned document, or graphic, converting it to PDF takes seconds — no software to install, no files uploaded anywhere.

Why Convert a JPG to PDF?

There are plenty of everyday reasons to convert images into PDFs:

Whatever your reason, converting images to PDF is quicker than most people think — and you don't need Photoshop or Acrobat to do it.

What Image Formats Does DocKiit Support?

DocKiit's image to PDF converter supports JPG and PNG files. Each image you add becomes one page in the final PDF — so if you add three images, you get a three-page PDF.

How to Convert JPG to PDF on DocKiit

Step 1: Open the JPG to PDF Tool

Head to DocKiit and select JPG to PDF from the homepage. This is a Pro feature — you'll need a DocKiit Pro account to access it.

Step 2: Add Your Images

Click Choose Files or drag and drop your images onto the page. You can add multiple images at once — JPG and PNG work. Each image will become one page in the output PDF.

Step 3: Choose Your Page Size

Select how you want the pages sized:

If you're printing the PDF, A4 or Letter will give you the cleanest result. If you just need the images in PDF format without any resizing, use Fit to image.

Step 4: Convert and Download

Hit Convert to PDF and your PDF downloads instantly to your device. All images are combined into a single file, in the order you added them.

Convert images to PDF privately — no upload needed

DocKiit Pro gives you access to JPG to PDF conversion, merging, compression, watermarking and more — all processed locally in your browser. USD $9.99/mo.

How to Convert JPG to PDF on Mac

Mac users can convert images to PDF for free using the built-in Preview app. Open your image in Preview, then go to File → Export as PDF and save. For multiple images, select them all in Finder, right-click, and choose Open With → Preview — then export the whole set as a PDF. It works well for simple conversions, though DocKiit gives you more control over page sizing.

How to Convert JPG to PDF on Windows

On Windows, open your image and use Print → Microsoft Print to PDF to save it as a PDF. For multiple images, this gets tedious fast — a browser-based tool like DocKiit is much quicker for batch conversions.

How to Convert JPG to PDF on iPhone or Android

Open your mobile browser, go to DocKiit, and follow the same steps. No app download needed — it works on any device with a modern browser. On iPhone you can also use the Files app to convert images to PDF natively, though it offers no page size control.

Frequently Asked Questions

Can I convert multiple images into one PDF?

Yes — you can and DocKiit combines them all into a single PDF, with each image as its own page.

Does converting to PDF affect image quality?

No — DocKiit embeds your images directly into the PDF without recompressing them, so quality is fully preserved.

Can I convert PNG files too, not just JPG?

Yes — DocKiit supports JPG and PNG. You can mix formats in the same conversion and they'll all be combined into one PDF.

What's the difference between A4, Letter, and Fit to image?

A4 and Letter are standard paper sizes — your image is fitted onto that page size, which may add small borders depending on the image dimensions. Fit to image makes the PDF page exactly the size of the image with no borders, which is useful when you want the PDF to match the image precisely.

Is it safe to convert images online?

With DocKiit, yes — your files never leave your browser. Everything is processed locally using JavaScript, so no image is ever sent to a server.

Can I reorder the images before converting?

To change the order, remove the images using the × button and re-add them in the order you want. The page order in the final PDF matches the order they appear in the list.
